#+title: Installing
|
|
* Set up
|
|
** If new host, follow [[file:hosts.org][Setting up a new host]]
|
|
** Open a nix-shell with dependencies
|
|
#+BEGIN_SRC bash
|
|
nix-shell -p git
|
|
#+END_SRC
|
|
** Obtain the flake
|
|
+ Via git clone
|
|
#+BEGIN_SRC bash
|
|
git clone https://git.samfelag.xyz/marc/samfelag.git
|
|
#+END_SRC
|
|
+ Via scp (in this case, from local to remote)
|
|
#+BEGIN_SRC bash
|
|
scp samfelag marc@remotehost:samfelag
|
|
#+END_SRC
|
|
** Copy the host ssh key
|
|
Obtain the host ssh *private* key. You can decrypt it using gpg:
|
|
#+begin_src bash
|
|
gpg -d secrets/ssh-keys/id_<host>.gpg > /etc/ssh/id_<host>
|
|
#+end_src
|
|
Copy the ssh keys to `/etc/ssh`
|
|
* Partition the disk
|
|
We'll partition the disk in the follwing way:
|
|
+ 512MB at the beginning for the boot partition
|
|
+ 8GB at the end for swap
|
|
+ The rest (at the middle) for the filesystem (/)
|
|
** Locate the disk
|
|
#+BEGIN_SRC bash
|
|
lsblk
|
|
#+END_SRC
|
|
** UEFI Boot
|
|
1. Create a GPT partition table
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/nvme0n1 -- mklabel gpt
|
|
#+END_SRC
|
|
2. Create the root partition
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/nvme0n1 -- mkpart primary 512MB -8GB
|
|
#+END_SRC
|
|
3. Create the swap partition
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/nvme0n1 -- mkpart primary linux-swap -8GB 100%
|
|
#+END_SRC
|
|
4. Create the boot partition
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/nvme0n1 -- mkpart ESP fat32 1MB 512MB
|
|
sudo parted /dev/nvme0n1 -- set 3 esp on
|
|
#+END_SRC
|
|
** MBR boot
|
|
1. Create a MBR partition table
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/vda -- mklabel msdos
|
|
#+END_SRC
|
|
2. Create the root partition
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/vda -- mkpart primary 1MiB -8GiB
|
|
#+END_SRC
|
|
3. Create the swap partition
|
|
#+BEGIN_SRC bash
|
|
sudo parted /dev/vda -- mkpart primary linux-swap -8GiB 100%
|
|
#+END_SRC
|
|
* Format the partitions
|
|
1. Root partition
|
|
#+BEGIN_SRC bash
|
|
sudo mkfs.ext4 -L nixos /dev/nvme0n1p1
|
|
#+END_SRC
|
|
2. Swap partition
|
|
#+BEGIN_SRC bash
|
|
sudo mkswap -L swap /dev/nvme0n1p2
|
|
#+END_SRC
|
|
3. Boot partition (if UEFI boot)
|
|
#+BEGIN_SRC bash
|
|
sudo mkfs.fat -F 32 -n BOOT /dev/nvme0n1p3
|
|
#+END_SRC
|
|
* Mount the filesystems
|
|
1. Root partition
|
|
#+BEGIN_SRC bash
|
|
sudo mount /dev/disk/by-label/nixos /mnt
|
|
#+END_SRC
|
|
2. Boot partition (if UEFI boot)
|
|
#+BEGIN_SRC bash
|
|
sudo mkdir -p /mnt/boot
|
|
sudo mount /dev/disk/by-label/BOOT /mnt/boot
|
|
#+END_SRC
|
|
3. Swap partition (if needed)
|
|
#+BEGIN_SRC bash
|
|
sudo swapon /dev/disk/by-label/swap
|
|
#+END_SRC
|
|
* Create the host nix configuration
|
|
If the host is not present under system/hosts, create a new folder for the host.
|
|
Check [[Setting up a new host]] for further documentation.
|
|
Generate the hardware configuration file, you can use nixos-generate-config as a base:
|
|
#+BEGIN_SRC bash
|
|
nixos-generate-config --dir <<host directory>> --no-filesystems
|
|
#+END_SRC
|
|
* Install nixos!
|
|
#+BEGIN_SRC bash
|
|
sudo nixos-install --impure --root /mnt --flake '.#reykjavik'
|
|
#+END_SRC
|
|
* Copy the ssh deploy key (again)
|
|
#+begin_src bash
|
|
cp ~/.ssh/id_<hostname> /mnt/home/marc/.ssh/id_<hostname>
|
|
#+end_src
|
|
* Initialization
|
|
Steps after reboot
|
|
** Set up the user
|
|
You'll set the root password during the installation. You can then reboot and use the installed OS. First thing you'll have to do is log in as root (via vultr dashboard) and set the password for your user:
|
|
#+BEGIN_SRC bash
|
|
passwd marc
|
|
#+END_SRC
|
|
** Log into tailscale
|
|
#+begin_src bash
|
|
sudo tailscale up
|
|
#+end_src
|
